Yourself! Er, Bombadil, anyway.

To none a slave, to some a master, - Certainly no one's slave but he has power over his borders

Who then is he,
that wanders after? - a very good question indeed.

The death of all,
and life for none,
yet who am I,
that stay's alone? - not quite sure what my reasoning is, here. But it sounds enigma-ish and thus Bombadil-ish.

Perhaps, they say,
I'm but a jest. - He could seem like a ridiculous, singing fellow.

Perhaps they're right,
I think, for lest
the watchers clear my path,
I will remain
a tool for laughs. - He could care less what other people think of him but he doesn't want he, his Goldberry, nor his lands bothered.

Is that it, perhaps?
